Three promises

Less paper. More clarity. Full control.

Stays with you.

Your documents live on your iPhone and nowhere else. No account, no cloud, no trackers – and everything the app recognises sits in an encrypted database.

Done in seconds.

Scan, tap a folder, saved. MR DocuS suggests the name, the date and the right folder on its own.

Find everything.

Every word in every document is searchable. Text recognition runs right on the device – even without internet.

How it works

From letterbox to folder. In seconds.

No setup, no learning curve. Three steps – and your paperwork is done.

Smart by default

Reads along. Thinks ahead. Reminds you.

MR DocuS understands what’s in front of you. A scan becomes a document with a clear name, in the right folder – complete with deadline and payment details.

  • Name and dateSender and document date are recognised and turned into a clear name.
  • The right folderInvoice, contract or official letter: the app suggests the matching folder.
  • Deadlines in viewDeadlines are recognised. If you like, MR DocuS reminds you in good time.
  • Payments in one tapCopy IBAN, amount and reference into your banking app with a single tap.

Recognised deadlines and amounts are suggestions. Please check them against the original.

Compression

Tiny files. Razor-sharp.

Every page is automatically saved as small as possible – but never smaller than legibility allows. That leaves room for thousands of documents.

  • Quality guardIt compares every page with the original, piece by piece. If legibility suffers, it automatically picks the next better level.
  • Crisp textText pages are stored as razor-sharp black and white, photos are compressed to fit.
  • Clean paperShadows and grey paper tones are evened out, blank pages detected.
  • No sliders at allThere’s no button for it and nothing to set. It just happens.

Tools

A whole office. In your pocket.

Sign, fill in, highlight, redact, reorder pages: every task has its own tool – clearly laid out, quickly done and always undoable.

Sign like with ink.

The stroke swells and thins like a fountain pen. Sign once and MR DocuS remembers your signature for the next document.

Try it: sign here – with mouse, finger or pen.

Redaction that’s really gone.

Redacted areas disappear for good – from the image and from the text underneath.

Image to PDF.

Pick photos, check the order, share them as one PDF. No detours.

And everything else that belongs.

FAQ

Good to know.

The most common questions – answered briefly and honestly.

Do I need an account?

No. Open the app and get started – no sign-up, no email address, no profile.

Where are my documents stored?

Only on your iPhone, in a protected area of the app. Titles, notes and recognised text are additionally stored in an encrypted database. There is no cloud.

Does MR DocuS work offline?

Yes. Scanning, text recognition, search and all tools run entirely on the device.

Does it sync between devices?

No, on purpose. Without a cloud there is no sync. To move, use your device backup or a ZIP file.

How do I move to a new iPhone?

Choose “Device backup” under More → Back up & move and your documents move with your iCloud or computer backup. Or back up everything there as a ZIP file and import it on your new iPhone.

What happens after the free month?

The subscription then costs €0.99 per month. Cancel before and you pay nothing. Without a subscription, viewing, searching, sharing, exporting and backing up stay free – only new documents need the subscription.

Does my subscription move to a new iPhone?

Yes, with the same Apple ID. MR DocuS usually notices on its own. Otherwise tap “Restore subscription” under More → Subscription.

How do I cancel?

In the app under More → Subscription → Manage subscription. Or on your iPhone under Settings → your name → Subscriptions.

Are recognised deadlines and amounts reliable?

They are suggestions that save you work. Please always check them against the original. MR DocuS is not legal or tax advice.

Does a scan replace the original?

Not in every case. Keep originals for as long as you are required to. MR DocuS is not an audit-proof archive for businesses.
